QLIAS W. SCHURMAN, OF CENTRAL BEDEQUE, PRINCE EDWARD ISLAND, CANAD A, ASSIGNOR OF ONE-HALF TO ALFQRD GRAHAM, OF BOSTON, MASSACHUSETTS.

- VEHICLE-LIGHT.

zc'ounty," province ofPrince Edward Island, '5 Canada, (whose post-oilice address is Be-- risque, Prince Edward Island, Canada,) have .invented an Improvement in Vehicle-Lights, of which the following description, in con Specification of 'Letters iatent.

- nection with the accompanying drawings, is.

a specification, like letters on the drawings "representinglike parts. I My present invention 18 an improved elec- '-tric light, intended primarily for horsedrawn vehicles, and especially adapted to be affixed to the shefts of a wagon or buggy,

" not only to furnish the vehicle with a light, but also to illuminate the roadway in front of the'horses feet, and. at the same time to be shielded from the drivers vision. '1 pre .32 3 for to utilize a relatively small. electric light,

which may be supplied. by; any suitable battery on the. vehicle itself arid which light willbe greatly magnified by a suitable parabolic reflector and a lens By employing a light which will consume but a small amount of current, 'I can provide a very inexpensive --aii('l"serviceable vehicle light, thus overcom- :"ing vthe many objections to equipping a horse-drawn vehicle with an electric search 80 light, and enabling a practicable, commercial article to be produced. This invention is of special importance at the present time, when the road laws of many States require that all U vehicles be "provided with lights as a safety 3 measure.

In the manufacture'of a vehicle lamp in accordance with my present invention, where economy is an important feature-1 use a snrall incandescent lamp and a reflector, and

4 provide iauy adjustable connection therewith, so that the lamp may be positioned iii just the right foci of the refiector and also held in this position through spring tension. Preferablythese springs constitute the means forsupplyiugfthe electric current to the lamp, and will "always maintain their contact despitefthe jolts, ,jars and vibrations incident toac'tua'l use Other details of invention, novel combi- 0 nations of parts, andfeatures of construet ion will beliereinafter more fully pointed out 211d claimed. 7 lleferri ngto ti -e drawings, illustrating a preferred embodiment of my invention,

power.

F'g. 2 is an enlarged side view of the lamp Fig. 3 being a cross sectional view on the hne33 of F g, 2:,

Fig. i is a. front view of the lamp and bracket; and

Fig. 5 is a view of the lamp socket holder.

InFig. 1 i have illustrated a fragmentary section of a wagon body 1 and a fore wheel 2 and axle 3 in conventional form, to which is secured the pole'for a team, or the shafts for a single horse, one of such shafts being indicated. as i. To the underside of a shaft a is secured by a bolt 5 a clamping bracket (3, which carries the light. Any suitable source of power, as a primary or storage battery, is fitted in the vehicle as indicated at 7, and wires 8 and 9 are led therefrom in any convenient way (illustrated diagrammatically in Fig. 1) to the light.

As illustrated in Figs, 2 and i, the bracket 6 has a depending portion 10 adapted to.

encircle the casing 11 of the vehicle light, I

being clamped thereto by a bolt 12 and nut 13, as shown. The bolt 5 may conveniently. be one of the regular bolts uniting the braces on the shaft 4 with a cross-piece, or may be a separate bolt, and it will be understood that a similar light may be carried under each side of a pair of shafts, if deemed desirable. With the light in this position, it is shielded by. the shaft l from the vision of the driver in the buggy as well .asfrom the animal drawing the vehicle, and yet is in proper position, as to height, location and use to illuminate the roadway immediately in advance of the vehicle.

My vehicle light itself comprises the casing a backing is carrying terminal posts 15 and '16 fo'r the wires8 and respectively, the lens it" lllCll'QllGCtOl 18. The rear por- 1 tion of the reflector 18 is formed as a thread- To .rlhin the, lens lit and the reiiccto'r'ldin position, I provided plurality of rings, 22, 23 and 24, which will hold the lens 17 and reflector 18 in assembled position. Preferably rings 22 and 2 are of fiber or leather, so as to prevent any noise or rattle in the device, while 2-l is a metallic spring to hold the parts in proper position. The binding posts to tend through the backing ll, and have secured on the inner ends springbrnshes 25 and it one adapted to contact with the neck 15) of the reflector. and the other contacts directly with the lead to the light 21. The threaded connection between the neck 15) and the socket 20 ot' the lamp enables the lamp to he positioned inwardly or outwardly relatively with the reflecting surface 27 of the reflector, so as to secure the best ell'eet and conserve all the illnminatimi from the relatively small lamp, throwing the rays directly through the lens 17. similar to the relleetor and lens on an automobile search light.

it will be seen that l have produced an ellieient and powerful small electric light, suitable for \eliieles. which can he manufactured at sli ht expense and allixed quickly directly to any horse-drawn vehicle.

The construction of the electric search light itself with the lamp socket held centrally of the relleetor and in :uljustable po sition. together with the rings to prevent vibration and noise between the reflector and the lens, are applicable to any electric search light. and therefore I wish to claim these features broadly. The further feature of having the retleetor. the lamp. the lens 17. and the washer 2:3, all held in yieldingly assembled position, to prevent noise, rattle, etc. is also of importance in any searchlight subject to constant jars and jolts and such yielding means consisting preferably of the electrical contacts supplying current to the lamp. thusgreatly simplil'ying the construcand 16 ex- BEST AVAILABLE coe tion. is of very decided importance in a light of this type.

llaving described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination. an electric light on the shaft of a horse-drawn vehicle, said light being arranged to be secured under ar d shadowed by a shaft of the vehicle, means to attaeh'the light under said shaft, said attaching means cooperating with the light and shaft to enabl the light to illuminate the roadway for both horse and driver, while said shaft shields the vision of both from the glare of the light, said light comprising a relatively small electric searehlight having an int-losing casting, a lens, and a re-, lleetor held by yielding means in said cas-i' ing. the attaching means unitingthe lamp and vehicle shaft consisting in a bracket clamp, detaehably secured to the shaft.

2. In emnbination, an electric light having an int-losing casing with its forward portion llanged inwardly, a lens adapted to be held in said casing against the flange, a reflector also held within said casing by yielding means aml adapted to retain the lens in contact with the inturned flange of the easing, yielding means between the lens and rellector to prevent noise and rattling, a relatively small electric light within the relleetor and means to supply current thereto. together with a vehicle shaft carrying said light. in position under the shaft to constitllte said shaft as a shield of the light from the driver.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
